Massive Impact Crater Found In Greenland

Perhaps this is what Firestone was looking for under the ice in North America.

Scientists uncover massive asteroid impact site under Greenland ice sheet

The remnants of an ice age asteroid that slammed into the Earth have been discovered under Greenland's Hiawatha Glacier.



A mile-wide, iron asteroid slammed into northern Greenland as early as 12,000 years ago, creating an impact site with an area similar to that of New York City.


The timing is suspiciously close.

"Hiawatha's Glacier" indeed is that anywhere near Tonto's Crevasse?

Me not know, Kemosabe.

It surely is an impact crater, but on site mineral analysis awaits to confirm. The timeline is c.12,000-3,000,000 years, so it's understandable that hope it's a Younger Dryas impact crater is high, but it's a big date range, until it isn't. I doubt there will be any shortage of funding to answer those questions!

As I recall one of the problems with Firestone's hypothesis was that there was no impact crater. His answer was that the crater was in the ice which subsequently melted. This one shows that ice is not going to stop a massive impactor from making a crater.

Wolf Creek in the Northern Territory, that huge crater in the Arizona desert and now Greenland. Why are none of these things found in convenient places? Such as the end of the Northern Line or a short distance from San Diego?

Perhaps you've heard this one?

As a Delta Air Lines jet was flying over Arizona on a clear day,
the co-pilot was providing his passengers with a running commentary
about landmarks over the PA system.

"Coming up on the right, you can see the Meteor Crater, which is a
major tourist attraction in northern Arizona. It was formed 50,000 years ago when a lump of
nickel and iron, roughly 150 feet in diameter and weighing 300,000
tons, struck the earth at about 40,000 miles an hour, scattering white-hot
debris for miles in every direction. The hole measures nearly a mile
across and is 570 feet deep."

From the cabin, a blond was heard to exclaim, "Wow! It just missed the highway!"

Here's the paper:

"But the researchers are relying on more than wishful thinking when it comes to confirmation of the dating, as there are multiple lines of evidence already supporting it:

The crater bottom is exceptionally jagged – if it occurred much earlier it is likely the bottom would be smoother due to the erosion from melting ice.

One previously drilled ice core in Greenland shows a spike in platinum about 12,900 years ago.

The aerial radar survey also showed that most of the ice in Hiawatha is perfectly layered through the past 11,700 years – but in the deepest layers the ice is disturbed and jumbled together. Furthermore, the team matched the jumble with debris-rich surface ice on Hiawatha’s edge that was previously dated to 12,800 years ago. “It was pretty self-consistent that the ice flow was heavily disturbed at or prior to the Younger Dryas,” one researcher notes."

Nice research, Shaw!

Thanks, Min! Great YouTube video at this link. There seems to be a very good chance that the Cape York iron meteorites, which were known to, and used to fashion iron tools by, Eskimos, are related to this crater.

Yes like the old Runnymede joke. "When was Magna Carta signed?" "1215 sir" - "Jeez honey, we just missed it by 15 minutes"
